[1] These assemblies fit Chrysler cranks
and will accept pulleys, crank triggers, and oil pump drives
designed for Chevrolet big block.
[2] Hubs are dimensioned to clear
the stock cast-in timing tab. The damper face for pulley mounting
will be forward of the OEM location by: .150” for 2-ring
internal balance, .450” for 3-ring internal balance,
.750” for 3-ring external balance. Hubs may be shortened
by the listed amount for internal balance and .600”
(.150” fwd of OEM) on external balance if the tab is
cleared, or order ATI cover with adjustable tab (part #916259).
2-ring internal balance can be installed in the OEM location
with minor clearancing of the timing tab and retain OE timing
mark.
[3] Hub has 2 3/16 wide keys at 180O and requires a #916261
spacer which is supplied with the hub. ATI manufactures a
one-piece billet hardcoated aluminum pulley (pt # 916263)with
the OEM 7-groove serpentine for accessories & an outboard
10 groove serpentine for blower drive. [4] Part # 916256 has
a .600 counterbore, Part # 916257 has .830 counterbore.
[5] Aluminum hub OEM front (part #916255) is OK for 2 ring
dampers.
[6] Cannot retain OE location. Must space out accessory pulleys
.750”.
[7] For 2 ring shell assembly, use part #918447E.
[8] Part # 918605E is a 2-ring shell assembly.
[9] Supplied with new lightweight
aluminum pulley to retain stock belt location.
[10] Specify shell assembly number and #916192 for aluminum
hub.
[11] For Paxton Supercharger, add part #SK157C(OEM Paxton
size) & SK157C2 (10% OD Paxton) for new aluminum pulley
with 7 rib / 8 rib. Retains OEM belt location.
[12] Not an OEM replacement for stock pulley location.

How
to read this chart |
 |
- Locate the correct manufacturer's chart
- Choose the specific engine application
listed down the left side of the chart
- Determine if the damper needs to be internally
or externally balanced ( external balance dampers are constructed
of steel only). Black bars that extend horizontally across
the entire chart designate these sections
- Determine if you need steel or aluminum
shells. Labels for this information are listed across the
top of the chart in columns 2 and 3.
- Once you have determined the shell material,
you need to find the outside diameter (OD) of the desired
steel or aluminum shell. Then choose between 2 or 3 rings
and the desired weight of the damper.
- From the far right section of the chart,
select either a steel or aluminum hub for your desired engine
application. To determine the correct damper assembly part
number that intersects is the correct damper assembly.
- Assembly part numbers that are color
coded correspond to the pulley mount bolt pattern listed
near the top of the charts.
